Dissociation Energies of Diatomic Molecules of the Transition Elements. II. Titanium, Chromium, Manganese, and Cobalt
摘要:
Using information derived from a combination of effusion and mass‐spectrometric techniques, the dissociation energy of Co2has been calculated from the ratio of dimeric and monomeric cobalt in equilibrium with the liquid asD00(Co2)=39±6 kcal. Upper limits to the dissociation energy of Ti2, Cr2, and Mn2are also estimated asD00(Ti2)<58 kcal,D00(Cr2)<44 kcal,D00(Mn2)<21 kcal. These results are correlated with the energy required to promote the atom to the lowest‐lying bonding or valence state of electron configuration 3dn—14s.
